WASHINGTON–Mortgage applications jumped nearly 11% last week as mortgage rates retreated, driving the strongest refinance activity in nearly four months, according to the Mortgage Bankers Association’s (MBA) Weekly Mortgage Applications Survey for the week ending Aug. 8.
The MBA reported its Market Composite Index, a measure of aggregate mortgage loan application volume, increased 10.9% on a seasonally adjusted basis from the prior week (10% unadjusted). That’s a significant increase from the 3.1% weekly gain reported a week earlier.

The MBA further reported:
- The Refinance Index was up 23% week over week — the largest single-week gain since April — and was 8% higher than the same week in 2024. Last week’s increase of 5% already marked a turnaround from three weeks of declines, the MBA said.
- The Purchase Index was up slightly — 1% — seasonally adjusted (1% unadjusted) from the previous week, but was still 17% higher than the same week a year ago. That follows a 2% adjusted gain the week prior, according to the MBA.
‘Borrowers Responded Favorably’
“The 30-year fixed mortgage rate declined to 6.67% last week, which spurred the strongest week for refinance activity since April,” MBA Vice President and Deputy Chief Economist Joel Kan said in a statement. “Borrowers responded favorably, as refinance applications increased 23%, driven mostly by conventional and VA applications.”
Kan additionally noted the refinance share of applications jumped to 46.5%, the highest level since early spring. He also highlighted that the average loan size for refinances rose significantly to $366,400, underscoring that borrowers with larger loan balances remain most sensitive to rate changes.
Flexing ARMs
The MBA analysis found adjustable-rate mortgages (ARMs) also saw a spike in demand, with applications up 25% to their highest level since 2022. The ARM share of total applications rose to nearly 10%, reflecting their comparative rate advantage over fixed loans.
When it comes the 30-year mortgage, the MBA noted that while down from the previous week, rates on the product weren’t yet attractive enough for would-be homebuyers. “Lower rates were not enough to entice more homebuyers back into the market, as purchase applications were only up around 1% over the week, although still stronger than last year’s pace,” Kan said in his statement.
